Hi Inge,
that looks like posterior hippocampus. We constrain the pial and white
surfaces to not move in non-cortical regions so that they don't contribute
to the volume/surface area of the ribbon. There's a label named
?h.cortex.label that is automatically created that gives the region of the
surface that is cortex (as opposed to ventricles, caudate, hippocampus,
etc...).
cheers,
Bruce

Hello list,
when I process on v3.05 I notice areas where the pial and wm surfaces
intersect, giving cortical thickness = 0. This is usually seen in the
medial temporal area.
Is this a known issue, and how should I deal with it?
See attached screenshots.
Have a nice day
